Never let common sense or caution get in your way, get back on the shop and make shavings!
That's my philosophy! There's been a constant layer of sawdust and wood shavings on my garage floor for over a year now. The only reason i sweep is to make room for more!!
As for caution, if we had too much of that we'd still be living in caves, walking everywhere, and eating nothing but veggies and nuts!
Sorry bout your hand though, if you're like the rest of us you'll be back at it long before the healing's done!
